[0021]Such asFigure 1-5As shown, this embodiment relates to an auxiliary paper feeding device of a scanner, which includes a paper feeding platform 1, and paper feeding baffles 2 are provided on the left and right sides of the paper feeding platform 1.
[0022]In this embodiment, a paper pressing sheet 3 is provided on the paper feed baffle 2. The paper pressing sheet 3 and the paper feed baffle 2 are used to perform a preliminary limit pressing on both ends of the paper to prevent the entire stack of soft paper from collapsing during the scanning and feeding process.
[0023]The paper pressing sheet 3 is embedded in the inner side wall of the paper feed baffle 2 and is hinged to the inner side wall of the paper feed baffle 2. Through this design, when scanning ordinary paper, the paper pressing plate 3 can be received into the paper feeding baffle 2; when the soft paper needs to be restricted, the paper pressing plate 3 can be opened, which is convenient for operation.
[0024]Specifically: In order to prevent the stowed paper plate 3 from obstructing the feeding of the paper to be scanned placed on the paper feeding platform 1, the paper feed baffle 2 is provided with an inset groove on the side wall corresponding to the paper plate 3, and the paper plate The bottom side of 3 is integrally formed with a hollow connecting column, and both ends of the connecting column are provided with hinge joints, and the hinge joint is integrally formed with a hinge column at the slot corresponding to the hinge joint. The paper pressing plate 3 is hinged through the hinge joint of the connecting column. The column can be folded and hinged in the embedding slot. By hingedly connecting the paper pressing plate 3 in the embedding groove, the user does not need to use the paper pressing plate 3 to hide the paper pressing plate 3 in the paper feed baffle 2 while ensuring paper storage. The beauty of the groove.
[0025]A return spring is arranged between the hinge interface at one end of the connecting column and the hinge column, and the paper pressing sheet 3 is elastically hinged in the insertion groove through the return spring. By setting the return spring, when the paper pressing piece 3 is fully opened, the paper pressing piece 3 can be jammed, preventing the paper pressing piece 3 from turning over by the force of the paper and affecting the pressing effect of the paper pressing board 3; When fully stowed, the paper pressing piece 3 can also be jammed, preventing the paper pressing piece 3 from turning over and opening.
[0026]In the actual production process, the top of the paper feed baffle 2 is provided with a handle groove 21 which is convenient for turning over the pressure sheet 3. The paper pressing sheet 3 has a protruding hand portion corresponding to the handle groove 21. In this way, the user can easily break the paper pressing sheet 3 from the paper feed baffle 2 through the handle groove 21 and the breaking of the hand.
[0027]In this embodiment, the paper feeding platform 1 is provided with a first paper feeding pallet 4 along the paper feeding direction, and the first paper feeding pallet 4 is retracted and arranged in the paper feeding platform 1. The retractable setting makes it convenient to pull out or close the first paper feeding tray 4, which is convenient to operate and does not occupy too much space. For ordinary paper, you can directly fold the first paper feed pallet 4 inside the paper feed platform 1; if it is a long paper that needs to be scanned, you can pull out the first paper feed pallet 4, so that longer paper Can be placed.
[0028]In the case of a long paper, the paper at the end away from the paper feed opening will be in closer contact with the first paper feed pallet 4, and the friction force will be relatively high. During the scanning process, the paper may not be fed. In this embodiment, a plurality of first pulleys 41 are provided on the top end of the first paper feeding tray 4. Through the arrangement of the first pulley 41, its friction is greatly reduced, the paper feeding is more convenient, and the scanning speed is ensured.
[0029]In the actual scanning process, sometimes a particularly long paper needs to be scanned. At this time, the first paper feed pallet 4 alone cannot meet the requirements. In this embodiment, the first paper feeding pallet 4 is provided with a second paper feeding pallet 5, and the end of the first paper feeding pallet 4 away from the paper feeding platform 1 along the paper feeding direction and the second paper feeding pallet 5 One end is hinged. Through such a design, the second paper feeding pallet 5 can be turned over from the first paper feeding pallet 4 through hinges, further extending the paper receiving platform. In order to facilitate the turning over of the second paper feeding pallet 5, a turning groove 51 is provided on the second paper feeding pallet 5. In this way, the user only needs to hold the reversing groove to turn the second paper feed pallet 5 over.
[0030]Wherein, the included angle formed by the second paper feeding pallet 5 with the first paper feeding pallet 4 after being turned over is 20-50°. For ultra-long paper, if the second paper feed pallet 5 and the first feed pallet 4 do not form an angle, they will extend out of the same plane. In this case, the paper will easily abut directly against the scanner due to gravity. The paper feed port is likely to cause wrinkles at the front end of the paper, which is not conducive to the protection of the original document. By setting to form a certain angle, the end of the ultra-long paper will slightly sag and hang on the second paper feed pallet 5, and this will not happen.
[0031]In order to ensure that the paper can be scanned smoothly on the second paper feeding pallet 5, a plurality of second pulleys 52 are provided on the top and bottom ends of the second paper feeding pallet 5 along the paper feeding direction. A plurality of first grooves 42 for accommodating the second pulley 52 are provided on the end of the first paper feeding tray 4 far away from the hinge. The first groove 42 can accommodate the second pulley 52 so that the second paper feeding tray 5 can be stored into the paper feeding platform 1 after being folded.
[0032]In this embodiment, in order to reduce the friction between the lowest layer of paper and the paper feeding platform 1, the first paper feeding pallet 4 and the second paper feeding pallet 5, it is convenient for the paper to enter the scanner for scanning smoothly. The platform 1, the first paper feed pallet 4 and the second paper feed pallet 5 have also been modified. Wherein, the paper feeding platform 1 is provided with at least one reinforcing rib 11 along the paper feeding direction, and a plurality of paper feeding pulleys 12 are provided in the reinforcing rib 11. The paper is placed on the paper feeding platform 1, and the middle part of the paper is usually tightly abutted with the paper feeding platform due to gravity. The stiffener 11 is provided to lift the middle part of the paper to facilitate paper feeding and ensure that the paper feeding process is not card. The first paper feed pallet 4 is also provided with multiple first reinforcement ribs along the paper feed direction on the side that abuts the paper. Its function is the same as the function of the reinforcement ribs 11 on the paper feed platform 1. Lift it up to facilitate paper feeding and ensure that the paper feeding process does not jam. The second paper feeding pallet 5 is also provided with a plurality of second reinforcing ribs along the paper feeding direction on the side that abuts the paper, and their functions are the same as the first reinforcing ribs.
[0033]The beneficial effects of the present invention are as follows: by arranging the paper pressing pieces on the paper feeding baffle on the left and right sides, the entire stack of paper can be prevented from collapsing, and the paper can be used as a limit; and the first paper feeding pallet lengthens The length of the paper feeding platform can better support longer paper and prevent the entire stack of paper from collapsing.
